IPC-7351B Naming Convention for Small Outline Transistors SOT23

SOP + Pitch + P + Lead Span Nominal X Height – Pin Qty

Example:

SOT95P237X117-3N_JEDEC_TO-236AA

SOT = Surface Mount Plastic Small Outline Transistor
95P – Pitch = 0.95mm
237 – Lead Span Nominal = 2.37mm
117 – Height = 1.17mm
3 – Pins Qty = 3
